Topic: Probleme mit Wayland

Guten Morgen zusammen,

ich habe testweise mal von X11 auf Wayland umgestellt.
Dabei ist mir ein Problem aufgefallen. Ich kann die Werkzeugleisten nicht am Rand wieder andocken.

Ich habe mal Beispielvideos angehangen. Ist das ein bekannter Fehler oder nur ein Problem bei mir?

Hallo Thomas,

See:

I'm think this was fixed on Qt 6.9 not on old Qt 5.15.x

Regards,
Laurent

Re: Probleme mit Wayland

I "m on Debian Sid with plasma6 with Wayland and Qt6.9.
If I need to re-stack the windows because I have moved them, I run this command to switch the compositor back to X11/xcb mode and restore my windows. After that, I can restart QET normally under Wayland.

Re: Probleme mit Wayland

Hi Laurent,

Sorry, but I think I'm too stupid to understand that right now.
According to the QElectrotech info, I have version QT 5.15 installed.
With 6.9, the problem should no longer exist?
How do I upgrade the version in QElectrotech? I installed it from the Ubuntu sources and then upgraded to V0100 according to your instructions.

Re: Probleme mit Wayland

This is a Qt 5 bug and I think is fixed on Qt 6.9 or 6.10 version?
For QET we need to wait when we compile it with Qt 6.X framework

Re: Probleme mit Wayland

Ah, okay, so that will be fixed in the future as soon as it is built with the new QT version? So it's just a matter of time? Will that come in via a normal update?

Re: Probleme mit Wayland

ok thank you a lot.
i will stay at X11 when im working with QET.

Re: Probleme mit Wayland

Or if you want to work under Wayland just edit /usr/share/applications/org.qelectrotech.qelectrotech.desktop

And change

Exec=qelectrotech %F

By

Exec=env QT_QPA_PLATFORM=xcb qelectrotech %F

Off course! you need to change this line in *.desktop after each QET package upgrade...

For users using Ubuntu snap see: https://github.com/qelectrotech/qelectr … issues/373
